$3\frac{1}{8}\ mi$

Step-by-step explanation:

we know that

Kyle walks 2 1/4 miles

Trinity walks 1 3/8 miles less than Kyle

Convert mixed number to an improper fraction

$2\frac{1}{4}\ mi= 2+\frac{1}{4}=\frac{2*4+1}{4}=\frac{9}{4}\ mi$

$1\frac{3}{8}\ mi= 1+\frac{3}{8}=\frac{1*8+3}{8}=\frac{11}{8}\ mi$

To find out the total distance they walk each morning, add the distance Kyle walks plus the distance Trinitry walks.

The distance Kyle walks is 9/4 miles

Find out the the distance Trinitry walks

Subtract 11/8 miles from the distance Kyle walks

$\frac{9}{4}\ mi-\frac{11}{8}\ mi=\frac{2*9-11}{8}=\frac{7}{8}\ mi$

Adds the distances

$\frac{9}{4}\ mi+\frac{7}{8}\ mi=\frac{2*9+7}{8}=\frac{25}{8}\ mi$

Convert to mixed number

$\frac{25}{8}\ mi=\frac{24}{8}+\frac{1}{8}\ mi=3\frac{1}{8}\ mi$
